To alla/710m it may concern State of lVest Virginia, have invented a`new and useful Scrap-Bundling Press, of which the following is aspecification.

The object of my invention is to provide an efficient mechanism by meansof which scrap, consisting to a great extent of sheet metal trimmings,etc., may be compressed into compact masses, usually called bundles, forconvenient handling.

The accompanying drawings illustrate my invention.

Figure 1 is a side elevation, in partial section, of a press embodyingmy improve ments, and Fig. 2 is a section largely on the line 2-2 of Fig. 1, the plane of section, however, being displaced as to themeasuring box, so as to show the same in section.

In the drawings, indicates a heavy main frame or housing comprising apair of sides or posts, and connecting ends; in the upper part of theframe 10 are vertical guides 11, between which is mounted a cross head12. About midway vertically of the frame 10, I connect the posts of theframe by heavy, ribbed plates 13, 13, which together with said posts,form a compression or die box 14, the bottom of which is formed by avertically movable cross head slidably. mounted in suitable verticalguides 16 formed in the lower part of housing 10. This lower crosshead15 is moved I vertically by means of a plunger 17, mounted in a cylinder18.

The head l5 is provided with depending rods 19 which project throughsuitable lguides formed in the lower end of housing 10, and these rods19 are provided with adjusting nuts 2O adapted to engage the housing, soas to limit the downward movement of the cross head 15, and also takethe load, resulting in this direction from compressing the scrap. Rods19 have their lower ends likewise provided with adjustable nuts 21, bymeans of which the upward stroke of cross head 15 may be controlled, soas to insure its perfect alinement with the chargin Hoor 22.

he cross head 12 is movable toward and from the die box 14 and is heldfirmly W'thin the box 14 by means of a plunger 25 and a cylinder 26,and, when held within the box it covers the scrap and forms the top ofbox.

In order to have the apparatus as compact as possible, and at the sametime provide means requiring only a minimum volume of the motive fluid,the plunger is made hollow in order to form a chamber 27 into which isprojected a cylinder 28, carried by the upper end of cylinder 26.lVithin cylinder 28 is a plunger 29, considerably smaller than theplunger 25, and this plunger 29 is connected to a crosshead 30 which isconnected by the vertical tierods 31, 31 with the crosshead 12, the said-rods projecting through suitable guides 32 formed in the upper end ofhousing 10 and provided at an intermediate point with adjustable nuts 33adapted to engage the upper member of housing 10 and thus limit thedownward movement of the crosshead 12.

Firmly connected to one of the vertical post-s of housing 10, by thetie-rods 35, is a cylinder 36 within which is mounted a plunger 37, theforward end of which is formed into a rectangular scrap-compressing die38`projecting through a suitable guide 38 formed in one of the posts ofhousing 10 and just above the level of the top of lower crosshead 15when in its lower position. Connectedv with plunger 37, by tie-rods 39(which are partially broken away in Fig. 1) and a crosshead 40, is aplunger 41 of smaller area than the plunger 37 and this plunger 41 ismounted in cylinder 42 carried by the cylinder 36.

Slidably mounted in suitable guides 45 upon the charging floor 22 is ascrap meter or measuring box 47 which, as shown in Fig. 2, is preferablyslightly tapered downwardly so as to facilitate the gravity discharge ofthe scrap therefrom. The meter box 47 is coupled to a piston rod 48, thepiston of which works in a suitable air cylinder 49, provided with theusual control valves and piping whereby the meter box may be readilyreciprocated to and from the operating plane of the press along thecharging floor 22.

The cylinders 18, 26, 28, 36, and 42 are all provided with supply pipesand operating valves, (not shown on the drawings,) in connection withtwo hydraulic systems, one of high pressure and one of low pressure.Cylinders 18, 28, and 42 are operated on thel low pres-sure systemexclusively,"v troduced into cylinder 36, and the comprescylinder 36 isoperated exclusively on the high pressure system, and7 cylinder 2d isoperated on both systems in the following manner z-The cylinder 28allows the cross.

heads 12 and 30, the plungers 25 and 29 and the rods 31 to descend bygravity as fast as the fluid is allowed to escape from said .cylinder28; while this is going on, the cylinder 26 will automatically be filledfrom a tank, not sho-wn on the drawings,'until'the crosshead 12 restsupon the scrap within the compression or die box. At this moment the lhigh pressureI is turned into thevcylinder 26,

which may force the crosshead .12 down 'sufliciently to bring thelock-nuts 33 in contact with the top of housing 10 and thus` bring thecrosshead 12 to al precise, predetermined level. -Whether the crosshead12 is enabled to reach this level, depends entirely on the quantity andnature of the scrap within the die box. It should be obvious, that themeter box plays an important part in gaging the Aquantity of scra tosuch' a degree as to allow the crosshea 12 to always descend to the samelevel. These several cylinders may receive any suitable motive fluid,although considering latitude of location, and exposure` of press towinter weather, I cant help considering oil the preferable fluid. Thecylinder 49, however, is more conveniently operated by compressed air orsteam, because-'a higher speed of movement is here desirable.

In use, the scrap meter 47 is filled with vthe requisite amount ofscrap, the various pieces being laid therein in such al relationship toeach other as the operator may elect. Thereupon, the lower crosshead 15is moved .upwardly to the level of the charging fldor 22, and the meterbox with its load of scra is brought in a positioncentral abovecrosshead 15, and in the space left open between the posts of housings.After this, crosshead 15 is lowered to the position shown in Fig. 1, thescrap, meanwhile, following the crosshead 15 downwardly by gravity fromthe meter box and without material displacement of its various portions.After the crosshead 15 has again arrived at itsflower osition the meterbox is withdrawn to its ormer position, and refilled while the pressproper 1s being operatedin the followin manner: The crosshead 12 is nowlowere to its proper position and held here by the Huid within cylinder26, as described before. In ordinary practice there is no attempt atmaterial compression of the scrap at this moment. When crosshead 12 hasbeen 'brought into position, pressure is insion die 38 is forcedlaterally into the box 14, between sides 18, lower crosshead 15 andupper crosshead 12, so as to compress the scrap into the compact bundleindicated at 50 in Fig. 1. Thereupon tbe die 38 and the upper crosshead12 are withdrawn, and the lower crosshead 15 together with the bundle isforced upwardly to the level of the charging ioor 22, and the bundle 50is automatically pushed aside, and away from the press by the meter box,now making a new forward movement for the next charge. By the use ofthis apparatus, I am able tov handle large quantities of scrap veryconveniently, and economically, andthe bundles, if of steel, are in sucha condition thatv they may be readily shipped without further binding ofany lnd, and may readily be put into the charging boxes of any openhearth furnace. f

I claim as my invention:

1. A scrap-bundling press comprising a main frame, a charging irioorassociated with said main frame, a bottom head vertically reciprocablein the main frame toward and from the charging floor, a` top headvertically reciprocable in the main frame toward and from the bottomhead,.and a compacting plunger projectable into and out vof the spacebetween the top and bottom heads.

2. A scrap-bundling press comprising a housing, a compression box, andtop and bottom crossheads completing said box and having verticalreciprocating motion.

3. A scrap-bundling press, comprising a housing, a compression box, top'and bottom crossheads movable toward and from the box, and acompression die projectable into and out of the space between top andbottom crossheads.

4. In a scrap bundling press,.a main body comprising two side posts andend sections therefor, and a die box formed by the posts of said ybodyand two plates connecting the posts.

5. In a scrap bundling press, a main body 4 comprising two side postsand end sections therefor, a die box formed by the posts of said bodyand two plates connecting the posts, and a guide formed through one ofsaid posts and leadin to the die box.

In witness whereo I have hereunto set my hand at Follansbee, Brookecounty, West Virginia, this 5th day of December, A.'D. one thousand ninehundredand thirteen. t
